When remembering a card, how is it reacting in the brain?

 How much time is necessary to memorize several indicated cards? What kind of thing has occurred in the brain to express an indicated card in a linguistic way? Please try and let’s think about it !

 Please don't compare with others and try for yourself. You'll be able to memorize many cards in a short time by repeating. And you’ll feel the limit of the time it takes to memorize the cards. Then, you'll challenge yourself and clear the limit.

Is there something good in remembering many cards through repetition ?

 We forget things less and less in our daily lives , an important appointment isn't forgotten any more or it is a good way to prevent (major) cognitive illness . That is something that still isn’t understood.  Let’s consider this question while trying this program .
